PsychiatryNLPKit.analysis.syntax_depth

PsychiatryNLPKit.analysis.syntax_depth(syntax_trees, sections=None)

Average syntax tree height per section.

Notes:

Theoretical basis - Reduced syntactic complexity predicts early schizophrenia onset (Morice & Ingram, 1983).

Args:

syntax_trees: Dict mapping section names to lists of constituency parse

trees.

sections: Sections to process. None processes all sections in

syntax_trees.

Returns:

Dict mapping section names to a dict with key "syntax_depth". Empty sections receive float("nan").
